Abstract
Purpose In Brazil, the city of Pelotas experienced an economic apex between the end of the nineteenth century and the beginning of the twentieth century, reflecting in the construction of several buildings. The aim of this article is to evaluate the state of degradation of the facades of the Old School of Agronomy Eliseu Maciel, using qualitative and quantitative indicators. Design/methodology/approach The study was divided into visual and photographic survey, damage map and subsequent application of the Degradation Measurement Method (MMD) and the Element Performance Index (Ip). Taking into consideration the evaluation of the building: through historical research and survey of damages. Finally, the building was framed at a level of degradation. Findings By calculating the average damage between the methods – damage map, MMD and Ip – a more faithful representation of the damage was obtained, since the values become balanced. The results show the potential of the use of the methods in the analysis of pathological manifestations in facades. Originality/value The originality of this article refers to the use of methods for evaluation of historical buildings. The authors believe that the methods described applied jointly provide the results about the state of degradation through nondestructive and low-cost analyses. The methods of surveying damage to Brazilian heritage are a little researched area. This work will hopefully be engaged by academics and professionals to help establish and promote broad government interest and investments.
